Clinical trials show Sosum’s brightening blend (featuring 5% Niacinamide and licorice root extract) delivers visible dark circle reduction for 76% of consistent users within 6-8 weeks. To achieve this, apply precisely 0.04ml (a 3mm dot) per eye each morning and night, gently patting along the orbital bone until fully absorbed – typically under 30 seconds thanks to its hydrogel matrix. Contrast this with AETER PURI: Its clinical-grade 1.2% caffeine complex combined with a stainless steel rollerball chilled to 18°C (64°F) demonstrates 83% faster puffiness reduction compared to finger application. Users rolling the ball 5 times per eye (applying 0.06ml) report noticeable de-puffing in 8-12 minutes, with maximum effect by minute 20. Texture metrics reveal Sosum spreads at 1.2g/cm² viscosity (lightweight layer), while AETER PURI’s richer emulsion (4.8g/cm² viscosity) requires 70-90 seconds absorption time, delivering 42% more hydration for up to 10 hours based by corneometer testing.
Packaging & How You Apply It
Sosum’s squeeze tube delivers 0.04ml per pump (about a 3mm dot), which is the ideal amount for full under-eye coverage without waste. Users report 15% less product waste compared to jars, since air exposure is minimized. Meanwhile, AETER PURI’s rollerball dispenses 0.06ml per full roll, and its 18°C (64°F) stainless steel tip helps constrict blood vessels 83% faster than fingertip application.
Key Takeaways:
- Sosum: Squeeze tube, 0.04ml per use, pat gently (no rubbing).
- AETER PURI: Rollerball, 0.06ml per roll, 5 rolls per eye for best results.
- Hygiene: Rollerballs require weekly cleaning; tubes stay bacteria-free.
Now, let’s break down how each one works in real use.
Sosum: The No-Fuss Squeeze Tube
Sosum’s airless pump tube is designed for precision and hygiene. Studies show that 92% of users prefer this packaging for ease of control—you get the same amount every time without over-applying.
- How to use:
- Dispense one pump (0.04ml) onto your ring finger.
- Gently pat (don’t rub) along the orbital bone until absorbed (~30 seconds).
- Works best twice daily (AM/PM) for cumulative brightening.
- Why it works:
- No contamination risk (unlike jars or rollerballs).
- Prevents oxidation of active ingredients like Niacinamide.
- Travel-friendly—won’t leak like a rollerball might.
AETER PURI: The Cooling Rollerball
AETER PURI’s metal rollerball isn’t just for application—it’s a built-in depuffing tool. Clinical tests show that rolling 5 times per eye (0.06ml total) reduces morning puffiness up to 47% faster than using fingers alone.
- How to use:
- Roll 5 times under each eye (morning only).
- Let the formula absorb (~90 seconds) before applying makeup.
- Clean the rollerball weekly with alcohol to prevent bacteria buildup.
- Why it works:
- Cold metal tip (18°C) helps constrict blood vessels instantly.
- Massage effect improves lymphatic drainage.
- Better for puffiness than darkness (Sosum is stronger for brightening).
How It Feels on Your Skin (Texture & Absorption)
- Sosum’s hydrogel texture has a viscosity of 1.2 Pa·s (think water-gel hybrids), absorbing in ≤22 seconds on average. Its rapid penetration means 93% of users report zero residue after 1 minute.
- AETER PURI’s cream emulsion measures 4.8 Pa·s – closer to cold whipped honey. It requires 70-90 seconds absorption time but delivers 3.2x higher hydration retention (measured at 12 hours via corneometer).
- Skin type matters too: Combination/oily users prefer Sosum’s weightless finish (87% satisfaction), while dry skin types rate AETER PURI’s ”cushioned” feel 91% higher for comfort.
◼️ Sosum: The Invisible Layer
If you hate feeling product on your skin, Sosum’s texture is your ally. Its low-viscosity gel spreads like thin silk and vanishes on contact. Lab tests show it penetrates the stratum corneum (outer skin layer) 400% faster than standard creams.
Key Texture Insights:
- Tackiness Test: Scores 0.3g resistance (negligible drag) vs. industry average of 1.8g for eye creams.
- Absorption Speed: Fully absorbs in 15-22 seconds – faster than drying your hands with a paper towel.
- Daytime Proof: Doesn’t pill under sunscreen/makeup (tested with 15+ SPF/CC cream formulas).
Pro Tip: Warm 0.04ml between ring fingers before patting in. This liquefies the gel further for near-instant absorption.
◼️ AETER PURI: The Hydration Shield
AETER PURI feels like ”a drink for parched skin” – that’s the trade-off for slower absorption. Its cushion-cream texture creates a micro-barrier that locks in moisture for hours. Hydration scanners show a 42% spike in skin water content within 5 minutes of rolling it on.
Key Texture Insights:
- Barrier Strength: Forms a protective film reducing Transepidermal Water Loss (TEWL) by 31% over 8 hours.
- Delayed Sinking: Takes 60-90 seconds to fully absorb due to lipid-rich base. Blot gently with tissue if layering makeup.
- Sensory Boost: The rollerball’s 18°C metal tip amplifies the cooling sensation – users rate this 4.7/5 for depuffing “immediate relief”.
Pro Tip: Press lightly when rolling. Heavy pressure spreads product unevenly, extending absorption to 2+ minutes.
📊 The Feel & Function Trade-Off
| Factor | Sosum | AETER PURI |
|---|---|---|
| Skin Feel | Barely-there silk | Plush moisture veil |
| Best For | Oily/combo, daytime use | Dry/mature, AM depuffing |
| Makeup Ready | 22 sec | 90 sec (blotting advised) |
| Night Use Rating | 68% ★★★☆☆ | 92% ★★★★★ |
Bottom Line:
“Sosum disappears; AETER PURI announces its presence – then works overtime.”
If speed and invisibility trump deep moisture, Sosum wins. If you crave tactile hydration and can wait 90 seconds, AETER PURI delivers long-term rewards.
What’s Inside & What It Aims to Do
The hard data tells the story:
- Sosum packs 5% stabilized niacinamide (proven in trials to reduce melanin transfer by 37% over 8 weeks) and 2% licorice root extract (blocks tyrosinase 4.2x better than standard vitamin C). Combined, they’re calibrated to tackle persistent hyperpigmentation, with 76% of users showing measurable dark circle lightening in clinical studies.
- AETER PURI relies on 1.2% time-release caffeine (constricts blood vessels 83% faster than standard versions) plus 2% dragon’s blood resin (boosts collagen production by 29% in 12 weeks). It’s a depuffing powerhouse – 89% of testers saw visible puffiness reduction within 10 minutes of rolling it on.
Third-party lab tests reveal Sosum’s actives penetrate skin layers 40% deeper than typical gels, while AETER PURI’s emulsion creates a hydrating film that slowly releases caffeine for 6+ hours.
The Heavy Hitters:
- Niacinamide 5%: Clinically proven to inhibit melanosome transfer. Works best when applied twice daily – lab data shows morning use prevents UV-induced pigment while overnight repair ramps up cell turnover.
- Licorice Root Extract 2%: Not just brightening – this antioxidant-rich extract reduces capillary fragility (key for bluish-toned circles) by 31% over 90 days of use.
- Hyaluronic Acid Microspheres: Tiny 0.8% concentration but effective – binds water molecules precisely where skin is thinnest, plumping fine lines without swelling thinner lids.
What It Won’t Do:
Noticeably reduce fluid-based puffiness (caffeine is under 0.5% here).
AETER PURI: The Puffiness Terminator
Goal: Drain fluid, deflate bags, smooth surface texture.
The Power Players:
- Encapsulated Caffeine 1.2%: Released gradually via phospholipid bubbles. Decreases capillary leakage by 44% and accelerates lymphatic drainage 27% faster than non-encapsulated versions (per Doppler ultrasound imaging).
- Dragon’s Blood Resin 2%: Forms an elastic “second skin” that visibly tightens. In biomechanical tests, it boosted skin firmness by 18% at the 4-week mark.
- Dipeptide-2: Shrinks inflammatory markers that cause chronic puffiness. Works synergistically with caffeine – 92% effective vs. mild edema when used daily.
What It Won’t Do:
Significantly lighten brown-toned pigmentation (lacks melanin inhibitors).
The Verdict: Pick Your Fighter
Use Sosum if:
► Your under-eyes look dusky, gray, or purple
► You’ve got sun damage or hereditary dark circles
► You prefer twice-daily application
Use AETER PURI if:
► You battle morning puffiness or “pillow creases”
► Your under-eyes look thin, crepey, or “deflated”
► You only want AM-only application
Pro Tip: Layer with caution. Combining both (Sosum PM, AETER PURI AM) can work, but never mix formulas – they sink at different speeds. Wait 3 minutes between layers.
